ABSTRACT:
A cooling system for a turbine airfoil of a turbine engine having suction and pressure side serpentine cooling channels formed between an internal support core and an outer wall of the turbine airfoil. The suction and pressure side serpentine cooling channels may be formed from legs extending in a general chordwise direction between leading and trailing edges of the airfoil. The suction and pressure side serpentine cooling channels may receive cooling fluids from a cooling fluid supply source through a cooling fluid inlet, pass the cooling fluids through the cooling system and exhaust the cooling fluids through a cooling fluid exhaust orifice proximate to the tip section. The cooling system is particularly suitable for use with low cooling fluid flow.
